Type ___ tires are used for high performance jet aircraft with their extremely high takeoff speeds.

• A. 6
• B. 9
• C. 8
• D. 7

Answer: (C)

Tire types are designated by numbers that reflect their speed rating and construction. For jets with extremely high takeoff speeds, you need a tire built to handle very high ground speeds and the resulting heat and loads. Type 8 tires are designed for this demanding service, offering a higher speed rating and tougher construction to cope with the energy generated during the takeoff roll and the braking after landing. Lower-number types wouldn’t provide the necessary strength and heat resistance for such high-speed operation, making them unsuitable for high-performance jet aircraft. That’s why Type 8 tires are used for these aircraft.
